The Foundation American Shetland is a subtype of the American Shetland.

The original American Shetland:
Foundation Americans have the same conformation that American Shetlands had during the 1950s, which means that they are less refined and are more heavily built than the Classic or Modern American Shetlands.

More specifically, their necks and legs are shorter and thicker, and their bodies are smaller and more compact than the bodies of the other two subtypes.
